There are many things that can lead to international conflict and war: Energy, influence, territory, etc. The Ukraine war is primarily territorial at any cost, as can be seen by Russia's willingness to lose Europe as a trading partner (including the now uselessness of most of its pipeline network since it was primarily directed to Europe), as well as almost all of Russia's complete surprise (including top government elites and the army brass) at the invasion in the first place. Belligerence from resource grievances fester for decades, and are telegraphed well in advance since pretty much the entire government will be on board before they start. It's also fairly obvious with Putin's continued nationalist rhetoric about reuniting "little Russia", and his continued rhetorical grievances with the West for over a decade. This is an obsession, planned in a way that nails everyone's colors to the mast. The causes for this war are primarily ideological (rebuilding Russia into its fabled great empire), not economic or strategic (although those do play minor roles, as always).
